DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
1.Introduction
This manual’s command descriptions are based on the software release 1.00. The commands listed here
are the subset of commands that are supported by the DGS-1510 Series SmartPro Switch.
Audience
This CLI Reference Guide is intended for network administrators and other IT networking professionals
responsible for managing the switch by using the Command Line Interface (CLI). The CLI is the primary
management interface to the DGS-1510 Series SmartPro Switch, which will be generally be referred to
simply as “the Switch” within this manual. This manual is written in a way that assumes that you already
have the experience and knowledge of Ethernet and modern networking principles for Local Area
Networks.

NOTICE: A notice indicates either potential damage to hardware or loss of data and tells you
how to avoid the problem.
CAUTION: A caution indicates a potential for property damage, personal injury, or death.
Command Descriptions
The information pertaining to each command in this reference guide is presented using a number of
template fields. The fields are:
• Description - This is a short and concise statement describing the commands functionality.
• Syntax - The precise form to use when entering and issuing the command.
• Parameters - A table where each row describes the optional or required parameters, and their
use, that can be issued with the command.
•Default - If the command sets a configuration value or administrative state of the Switch then any
default settings (i.e. without issuing the command) of the configuration is shown here.
•Comma n d Mode - The mode in which the command can be issued. These modes are described
in the section titled “Command Modes” below.
• Comma n d Default Level – The user privilege level in which the command can be issued.
• Usage Guideline - If necessary, a detailed description of the command and its various utilization
scenarios is given here.
•Example(s) - Each command is accompanied by a practical example of the command being
issued in a suitable scenario.
Command Modes
There are several command modes available in the command-line interface (CLI). The set of commands
available to the user depends on both the mode the user is currently in and their privilege level. For each
case, the user can see all the commands that are available in a particular command mode by entering a
question mark (?) at the system prompt.
The command-line interface has five pre-defined privilege leve ls:
•Basic User - Privilege Level 1. This user account level has the lowest priority of the user
accounts. The purpose of this type of user account level is for basic system checking.
•Adv anced U se r - Privilege Level 3. This user account level is allowed to configure the terminal
control setting. This user account can only show limited information that is not related to security.
•Power User - Privilege 8. This user account level can execute fewer commands than operator,
including configuration commands other than the operator level and administrator level
commands.
•Operator - Privilege Level 12. This user account level is used to grant system configuration rights
for users who need to change or monitor system configuration, except for security related
information such as user accounts and SNMP account settings, etc.
2
DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
•Administrator - Privilege Level 15. This administrator user account level can monitor all system
information and change any of the system configuration settings expressed in this configuration
guide.
The command-line interface has a number of command modes. There are three basic command modes:
• User EXEC Mode
• Privileged EXEC Mode
• Globa l Configuration Mode
All other sub-configuration modes can be accessed via the Global Configuration Mode.
When a user logs in to the Switch, the privilege level of the user determines the command mode the user
will enter after initially logging in. The user will either log into User EXEC Mode or the Privileged EXEC Mode.
• Users with a basic user level will log into the Switch in the User EXEC Mode.
• Users with advanced user, power-user, operator or administrator level accounts will log into the
Switch in the Privileged E XEC Mode.
Therefore, the User EXEC Mode can operate at a basic user level and the Privileged EXEC Mode can
operate at the advanced user, power-user, operator, or administrator levels. The user can only enter the
Global Configuration Mode from the Privilege d EX EC Mode. The Global Configuration Mode can be
accessed by users who ha ve operator or administrator level user accounts.
As for sub-configuration modes, a subset of those can only be accessed by users who have the highest
secure administrator level privileges.
The following table briefly lists the available command modes. Only the basic command modes and some
of the sub-configuration modes are enumerated. The basic command modes and basic sub-configuration
modes are further described in the following chapters. Descriptions for the rest of the sub-configuration
modes are not provided in this section. For more information on the additional sub-configuration modes,
the user should refer to the chapters relating to these functions.
The available command modes and privilege levels are described below:
Command Mode/
Privilege Level
User EXEC Mode /
Basic User level
Purpose
This level has the lowest priority of the user accounts. It is provided only
to check basic system settings.
Privileged EXEC Mode /
Advanced User level
Privileged EXEC Mode /
Power User level
Privileged EXEC Mode /
Operator level
Privileged EXEC Mode / This level is identical to privileged EXEC mode at the operator level,
This level is allowed to configure the terminal control setting. This user
account can only show limited information that is not related to security.
This level can execute less commands than operator, include the
configure commands other than the operator level and administrator
level commands.
For changing both local and global terminal settings, monitoring, and
performing certain system administration tasks. The system
administration tasks that can be performed at this level except for any
security related information.

VLAN Configuration Mode For applying settings to a VLAN.
IP Access-List Configuration
Mode
For applying global settings, except for security related settings, on the
entire switch. In addition to applying global settings on the entire switch,
the user can access other sub-configuration modes from global
configuration mode.
For applying global settings on the entire switch. In addition to applying
global settings on the entire switch, the user can access other subconfiguration modes from global configuration mode.
For applying interface related settings.
For applying VLAN interface related settings.
For specifying filtering criteria for an IP access list.
User EXEC Mode at Basic User Level
This command mode is mainly designed for checking basic system settings. This command mode can be
entered by logging in as a basic user.
Privileged EXEC Mode at Advanced User Level
This command mode is mainly designed for checking basic system settings, allowing users to change the
local terminal session settings and carrying out basic network connectivity verification. One limitation of
this command mode is that it cannot be used to display information related to security. This command
mode can be entered by logging in as an advanced user.
Privileged EXEC Mode at Power User Level
User logged into the S witc h in privileged EXEC mode at this level can execute fewer commands than
operator, including the configuration commands other than the operator level and administrator level
commands. The method to enter privileged EXEC mode at power user level is to login to the Switch with
a user account that has a privileged level of 8.
Privileged EXEC Mode at Operator Level
Users logged into the Switch in privileged EXEC mode at this level can change both local and global
terminal settings, monitor, and perform system administration tasks (except for security related
information). The method to enter privileged EXEC mode at operator level is to login to the Switch with a
user account that has a privilege level of 12.
Privileged EXEC Mode at Administrator Level
This command mode has a privilege level of 15. Users logged in with this command mode can monitor all
system information and change any system configuration settings mentioned in this Configuration Guide.
The method to enter privileged EXEC mode at administrator level is to login to the Switch with a user
account that has a privilege level of 15.
Global Configuration Mode
The primary purpose of the global configuration mode is to apply global settings on the entire switch.
Global configuration mode can be accessed at operator or administrator level user accounts. However,
security related settings are not accessible at operator user account. In addition to applying global
settings on the entire switch, the user can also access other sub-configuration modes. In order to access
the global configuration mode, the user must be logged in with the corresponding account level and use
the configure terminal command in the privileged EXEC mode.
In the following example, the user is logged in as an Administrator in the Privileged EXEC Mo de and us es
the configure terminal command to access the Global Configuration Mode:
4
DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
Switch# configure terminal
Switch(config)#
The exit command is used to exit the global configuration mode and return to the privileged EXEC mode.
Switch(config)# exit
Switch#
The procedures to enter the different sub-configuration modes can be found in the related chapters in this
Configuration Guide. The command modes are used to configure the individual functions.
Interface Configuration Mode
Interface configuration mode is used to configure the parameters for an interface or a range of interfaces.
An interface can be a physical port, VLAN, or other virtual interface. Thus, interface configuration mode is
distinguished further according to the type of interface. The command prompt for each type of interface is
slightly different.
VLAN Interface Configuration Mode
VLAN interface configuration mode is one of the available interface modes and is used to configure the
parameters of a VLAN interface.
To access VLAN interface configuration mode, use the following command in global configuration mode:
By default, there is no user account created on this switch. For security reasons, it is highly recommended
to create user accounts to manage and control access to this switch’s interface. This section will assist a
user with creating a user account by means of the Command Line Interface.
In the above example we had to navigate and access the username command.
•Starting in the User EXEC Mode we enter the command enable to access the Privileged EXEC
Mode.
•After accessing the Privileged EXEC Mode, we entered the command configure terminal to
access the Global Configuration Mode. The username command can be used in the Global
Configuration Mode.
•The command username admin password admin creates a user account with the username of admin and a password of admin.
•The command username admin privilege 15 assigns a privilege level value of 15 to the user
account admin.
•The command line console allows us to access the console interface’s Line Configuration Mode.
5
DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
•The command login local tell the Switch that users need to enter locally configured login
credentials to access the console interface.
Save the running configuration to the start-up configuration. This means to save the changes made so
that when the Switch is rebooted, the configuration will not be lost. The following example shows how to
save the running configuration to the start-up configuration.
Switch#copy running-config startup-config
Destination filename startup-config? [y/n]: y
Saving all configurations to NV-RAM.......... Done.
Switch#
After the Switch was rebooted, or when the users logs out and back in, the newly created username and
password must be entered to access the CLI interface again, as seen below.

Interface Notation
When configuration the physical ports available on this switch, a specific interface notation is used. The
following will explain the layout, terminology and use of this notation.
In the following example, we’ll enter the Global Configuration Mode and then enter the Interface
Configuration Mode, using the notation 1/0/1. After entering the Interface Configuration Mode for port 1,
we’ll change the speed to 1 Gbps, using the speed 1000 command.
In the above example the notation 1/0/1 was used. The terminology for each parameter is as follows:
•Interface Unit’s ID / Open Slot’s ID / Port’s ID
The Interface Unit’s ID is the ID of the stacking unit without the physical stack. If stacking is disabled or
this unit is a stand-alone unit, then this parameter is irrelevant. The Open Slot’s ID is the ID of the module
plugged into the open module slot of the Switch. The DGS-1510 Series doesn’t support any open
6
DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
modules slots, thus this parameters will always by zero for this switch series. Lastly, the Port’s ID is the
physical port number of the port being configured.
In summary the above example will configure the stacked switch with the ID of 1, with the open slot ID of
0, and the physical port number 1.
Error Messages
When the users issue a command that the Sw itch does not recognize, error messages will be generated
to assist users with basic information about the mistake that was made. A list of possible error messages
are found in the table below.

Command Mode
Line Configuration Mode.
Command Default Level
Level: 15.
Usage Guideline
For Console and Telnet access, when AAA is enabled, the line uses rules configured by the AAA module.
When AAA is disabled, the line uses the following authentication rules:
• When login is disabled, the user can enter the line at Level 1.
• When the by password option is selected, after inputting the same password as the command
password, the user enter the line at level 1. If the password wasn’t previously configured an error
message will be displayed and the session will be closed.
•When the username and password option is selected, enter the username and password
configured by the username command.
Specifies that the line login method will be login.
Specifies that the line login method will be local.
For SSH access, there are three authentication types:
• SSH public key,
• Host-based authentication, and
• Password authentication.
The SSH public key and host-based authentication types are independent from the login command in the
line mode. If the authentication type is password, the following rules apply:
14
Example
DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
• When AAA is enabled, the AAA module is used.
• When AAA is disabled, the following rules are used:
o When login is disabled, the username and password is ignored. Enter the details at Level
1.
o When the username and password option is selected, use the username and password
setup by the username command.
o When the password option is selected, the username is ignored but a password is
required using the password command to enter the line at level 1.

3-1 clear dot1x counters
This command is used to clear 802.1X counters (diagnostics, statistics and session statistics).
This command is used to clear 802.1X counters (diagnostics, statistics and session statistics).
Specifies to clear 802.1X counters (diagnostics, statistics and session
statistics) on all interfaces.
Specifies to clear 802.1X counters (diagnostics, statistics and session
statistics) on the specified interface. Valid interfaces are physical ports
(including type, stack member, and port number).
(Optional) Specifies a series of interfaces, or separate a range of
interfaces from a previous range. No space is allowed before and after
the comma.
(Optional) Specifies a range of interfaces. No space is allowed before
and after the hyphen.
Example
This example shows how to clear 802.1X counters (diagnostics, statistics and session statistics) on the
Ethernet port 1/0/1.
This command is used to configure the direction of the traffic on a controlled port as unidirectional (in) or
bidirectional (both). Use the no form of the command to reset to the default setting.
dot1x control-direction {both | in}
no dot1x control-direction
Parameters
24
DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
both
in
Default
By default, this option is bidirectional mode.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
This command is only available for physical port interface configuration. If the port control is set to forceauthorized, then the port is not controlled in both directions. If the port control is set to auto, then the access to the port for the controlled direction needs to be authenticated. If the port control is set to forceunauthorized, then the access to the port for the controlled direction is blocked.
Suppose that port control is set to auto. If the control direction is set to both, then the port can receive
and transmit EAPOL packets only. All user traffic is blocked before authentication. If the control direction
is set to in, then in addition to receiving and transmitting EAPOL packets, the port can transmit user traffic
but not receive user traffic before authentication.
Example
Specifies to enable bidirectional control for the port.
Specifies to enable in direction control for the port.
This example shows how to configure the controlled direction of the traffic through Ethernet eth1/0/1 as
unidirectional.
This command is used to reset the IEEE 802.1X parameters on a specific port to their default settings.
